As I have stated at the beginning of this BIM process, in order to insure an effective collaboration, all team members had to be part of this process and that includes the MEP fabricators. When I visited the selected HVAC fabricator with a mission to get them on board the BIM process, I was amazed with the 3D technology already in place by some fabricators. The HVAC sub contractor and fabricator played a major role in this process. They were not only using 3D parametric technology to demonstrate the complexity of the HVAC systems, this technology was also implemented to drive their plasma cutting and pipe bending machines directly from the 3D BIM.
Funds were allocated to the general contractor for the purchase of BIM software applications, training and creating the 3D MEP product data for those sub contractors that were not trained in 3D technology. This was a significant commitment by the owner and a requirement for achieving successful results. Unfortunately, only the selected HVAC fabricators and in part the electrical contractor took the opportunity of learning and implementing the 3D technology. The plumbing, fire protection and site utilities were the responsibility of View By View. The routing process and coordination of MEP is a complex task.
